DEWALT Power Tools Portable Construction Circular Saw Blade 165 x 20mm x 24T DT1934-QZ

A 165mm diameter circular saw blade with a 20mm bore and 24 teeth, designed for use with portable circular saws on construction sites. It is intended for first-fix work where cut finish is less important, including cutting rough or re-used timber and composite materials.

The carbide teeth are impact resistant, helping to withstand contact with embedded nails or other foreign objects without chipping. A wedge shoulder helps protect the carbide from nail impact, while Alternate Top Bevel (ATB) grind teeth with a +10° rake angle give sharp, clean cutting edges that reduce splintering. Ribbed heat vents allow the blade to run cooler, reducing flexing and binding during use. The plate thickness is 1.2mm with a kerf thickness of 1.8mm, and the arbor includes a diamond knock-out for compatibility with different machines.
